UV glass looks cool, but that’s not the only reason we use it. There’s a practical purpose too. You see, the UV Concentrate 420 Jar blocks all visible light from hitting your concentrate. So what does that mean? Awesomeness. And protection from premature degrading of your meds.If you want safe and if you want style, you want a UV Concentrate Jar from 420 Science. The shallow bowl is easy to scrape out. And, since it’s glass, you don’t have to worry about adding some unwanted plastic to your meds. Which is nice. It’s one less thing to worry about so you can concentrate on your concentrates.
